Current work in the Microfluidics Research Lab run by Dorian Liepmann spans from fundamental research to biomedical device development. Fundamental understanding is critical for optimizing new designs. Optimizing plasma separation from blood for Luke Lee's SIMBAS biosensor requires an understanding of blood flow. We are also working on the use of hot embossing for new devices and have developed new ways to both create and embed nickel electrodes into microchannels during fabrication. Hot embossing makes it possible to create functional plastic devices using a wide range of materials without the limits associated with PDMS.
